Hello my lovely flowers & welcome to a story that for once isn't Black Butler! 
I just surfing through the web until I saw that pic up there. I had to, okay? 
This first part is just info about the book and stuff.. may be pointless.
~~~~~~~~~~~~~~~~~~~~~~~ 

1.) Roger is Jessie's (Jessica) older brother. 

2.) There may be a lemon in here. 

3.) The pic below is what reader-chan is wearing.
Ignore the leather jacket & the skirt can be pants to.

4.) Reader is a humanoid cat toon. Kind of like if she were a character from Sly Cooper. (And since you most of you had a problem with being a neko, this is the only change I'm making. You are still a cat in this book. Don't like it? The back button is up there.)  

5.) Reader has a black trench coat and fedora. 

~~~~~~~~~~~~~~~~~~~~
I hope you guy enjoy the first chapter when it comes out. 
Stay chill my Black Roses. 
Bye bye ^^
